APPENDIX
APPENDIX
ESD Guidelines
What does ESD mean?
Virtually all present-day modules incorporate highly integrated MOS devices or
components. For technological reasons, these electronic components are very sensitive to
overvoltages and consequently therefore to electrostatic discharge:
These devices are referred to in German as Elektrostatisch Gefährdeten
Bauelemente/ Baugruppen: ºEGBº
The more frequent international name is:
ºESDº (E lectrostatic Sensitive Device)
The following symbol on plates on cabinets, mounting racks or packages draws attention to
the use of electrostatic sensitive devices and thus to the contact sensitivity of the
assemblies concerned:
ESDs may be destroyed by voltages and energies well below the perception threshold of
persons. Voltages of this kind occur as soon as a device or an assembly is touched by a
person who is not electrostatically discharged . Devices exposed to such overvoltages cannot
immediately be detected as defective in the majority of cases since faulty behavior may occur
only after a long period of operation.
Precautions against electrostatic discharge
Most plastics are capable of carrying high charges and it is therefore imperative that they be
kept away from sensitive components.
When handling electrostatic sensitive devices, make sure that persons, workplaces and
packages are properly grounded

23
APPENDIX
Handling ESD assemblies
A general rule is that assemblies should be touched only when this cannot be avoided owing
to the work that has to performed on them. Under no circumstances should you handle
printed-circuit boards by touching device pins or circuitry.
You should touch devices only if
● you are grounded by permanently wearing an ESD wrist strap or
●you are wearing ESD shoes or ESD shoe-grounding protection straps in conjunction
with an ESD floor.
Before you touch an electronic assembly, your body must be discharged. The simplest way
of doing this is to touch a conductive, grounded object immediately beforehand ± for
example, bare metal parts of a cabinet, water pipe etc.
Assemblies should not be brought into contact with charge-susceptible and highly insulating
materials such as plastic films, insulating table tops and items of clothing etc. containing
synthetic fibers.
Assemblies should be deposited only on conductive surfaces (tables with an ESD coating,
conductive ESD cellular material, ESD bags, ESD shipping containers).
Do not place assemblies near visual display units, monitors or television sets (minimum
distance to screen > 10 cm).
Measuring and modifying ESD assemblies
Perform measurements on ESD assemblies only when
● the measuring instrument is grounded ± for example, by means of a protective conductor
± or
● the measuring head has been briefly discharged before measurements are made with a
potential-free measuring instrument ± for example, by touching a bare metal control
cabinet.
When soldering, use only grounded soldering irons.
Shipping ESD assemblies
Always store and ship assemblies and devices in conductive packing ± for example,
metallized plastic boxes and tin cans.
If packing is not conductive, assemblies must be conductively wrapped before they are
packed. You can use, for example, conductive foam rubber, ESD bags, domestic aluminum
foil or paper (never use plastic bags or foils).
With assemblies containing fitted batteries, make sure that the conductive packing does not
come into contact with or short-circuit battery connectors. If necessary, cover the connectors
beforehand with insulating tape or insulating material.
